Denmark: A collaborative effort involving the Technological Institute, DTU, FLSmidth Cement, and Lhoist is underway in Denmark to test a new technology designed to significantly reduce CO2 emissions in the cement industry. The initiative, known as the Newcement project, is part of the INNO-CCUS partnership which embraces projects focusing on carbon capture, utilisation and storage (CCUS) and is supported by an investment of US$1.12m from the Innovation Fund. Jens Christiansen, Section Manager at the Technological Institute and Project Manager of the collaboration, aims for the technology to move from laboratory tests to a full-scale demonstration in a real cement production plant.
Türkiye: The Turkish cement industry needs to invest approximately US$30bn to achieve its net-zero carbon goal by 2053, according to sector representatives. Additionally, around US$2bn is required to adhere to the European Union’s Carbon Border Adjustment Mechanism (CBAM), according to Fatih Yücelik, chair of the Turkish Cement Manufacturers’ Association (TÜRKÇİMENTO).
Yücelik said “The most important issue for us this year is carbon emissions. The amount of investments to be made swiftly in transformation and efficiency work to overcome the barriers created by the CBAM is around US$2bn. However, under the current situation, it is difficult for us to find this financing.”
There are 77 factories producing cement in Türkiye, according to Yücelik. “They all use kilns which heavily consume energy. We are establishing waste heat recovery facilities. The amount of electricity generated by those units can power 618,000 homes,” he said. The industry also faces rising operational costs, with energy comprising about 80% of these expenses.

Global Cement and Concrete Association and China Cement Association to collaborate for cement decarbonisation
01 February 2024World: The Global Cement and Concrete Association (GCCA) has signed a new agreement with the China Cement Association (CCA). The agreement constitutes an historic ‘partnership pledge’ to accelerate cement decarbonisation globally in 2024 – 2026. The partners says that their collaboration will contribute to the development and launch of the upcoming China Cement Carbon Neutrality Roadmap. Equipment supplier Sinoma International Engineering and the European Cement Research Academy (ECRA) will also help to develop the roadmap. The GCCA previously launched its own global net zero roadmap in 2021. Together, GCCA and CCA members account for 90% of global cement production in capacity terms.
GCCA CEO Thomas Guillot, said “The world needs leadership and collaboration like never before, especially on addressing the key issue of our time, climate change. This agreement between the China industry and the global industry is a signal to the world that we stand ready to deliver the essential decarbonised building materials that our planet needs. Cement and concrete enable the key infrastructure, thriving and resilient communities, clean water, safe homes and the shift to clean energy that are essential to a future sustainable world.”
CCA Executive president Kong Xiangzhong said “This important agreement marks a win-win cooperation, and shows where we can collaborate effectively to bring insights, technical know-how and greater focus to our shared decarbonisation mission. I am sure this will create a mutually-beneficial and long-term partnership that will be crucial in building a more sustainable world.”
UK: Aggregate Industries has successfully removed gas duct sections from the electrostatic precipitation filter at its Cauldon cement plant in Staffordshire. This will make way for the installation of a new CTP Team process kiln bag filter, following an annual shutdown.
Cauldon plant capital expenditure manager Mark Powling said “The new bag filter not only provides the best available technology, but will enable the Cauldon plant to optimise its plant performance, driving its decarbonisation and alternative fuel strategies. Thanks to the project team for their efforts and hard work to date.”
Holcim’s ECOCycle construction-demolition material recycling technology named Circularity Lighthouse
17 January 2024Switzerland: McKinsey & Company and the World Economic Forum have recognised Holcim’s ECOCycle recycling technology for construction-demolition material (CDM) as a "Circularity Lighthouse in the Built Environment." ECOCycle technology can process 100% of CDM input into new building materials with 75% lower CO2 emissions than traditional alternatives.
Chief sustainability officer Nollaig Forrest said “Circularity is a game changer to decarbonise buildings at scale. At Holcim we are operating over 100 ECOCycle recycling centres globally to drive circular construction. With our advanced recycling of CDM, we can already reduce the CO2 footprint of cement by up to 40%. This is just the beginning; as we innovate and partner across the value chain to evolve building norms, we aim to accelerate the shift to circular construction in all metropolitan areas where we operate.”
Iranian cement plants use mazut as fuel amid gas shortage
15 January 2024Iran: 70% of cement plants by capacity were reportedly using the low-quality heavy fuel oil mazut as cement fuel on 13 January 2024. Iranian Labour News Agency has reported that plants transitioned to the fuel from natural gas amid an on-going gas shortage. This has led to a rise in costs and increased pollution from cement plants.
Iran’s Cement Industry Employers’ Association said that the industry’s supply of natural gas has dropped to 7Mm3/yr, from 27M3/yr normally.
Germany: Rohrdorfer Zement has fired up a pilot clay tempering unit at its Rohrdorf cement plant in Bavaria. The project has received Euro8.65m in funding from the German Federal Ministry for Economic Affairs and Climate Action and the EU. It is one of a number of industrial projects under the EU’s Euro800bn NextGenerationEU post-Covid-19 economic recovery instrument. Sources of heat for the pilot unit at the Rohrdorf cement plant include waste heat from the plant’s clinker line. If the pilot succeeds, the introduction of tempered clay into cement production at the site will follow. This will entail the construction of an on-site full-scale clay tempering plant. Rohrdorfer Zement says that this would reduce the plant’s CO2 emissions by 16 – 18%, or by 30% if it achieves carbon neutral clay tempering through the use of green hydrogen.
Rohrdorfer’s dedicated Net Zero Emissions Labs team is working to turn the Rohrdorf cement plant carbon neutral by 2038. Other initiatives include the installation of carbon capture systems at the Rohrdorf plant and another in Austria, and participation in the H2-Reallabor Burghausen hydrogen partnership.
Regarding the latest pilot, Rohrdorf Net Zero Emissions Labs project leader Helmut Leibinger said “As a cement component, tempered clays make a significant contribution to CO2 mitigation. With the pilot project of process-integrated tempered clay, we are taking not just a step in our decarbonisation roadmap, but a leap.”
Holcim Deutschland upgrades Beckum cement plant
09 January 2024Germany: Holcim Deutschland has announced for the ‘most extensive’ modernisation of its Beckum cement plant to date. Local press has reported that the modernisation will commence with the installation of a Euro20m pendulum cooler to replace the plant’s existing tube cooler. The new cooler will reduce the plant’s CO2 emissions and make separated CO2 better suited for capture, according to the producer. The Beckum cement plant is the site of an on-going carbon capture trial.
General manager Jan Kristof Peters said “We want to implement all construction work as quickly as possible and with as little noise pollution as possible for the neighbourhood. As in previous years, we ask for our neighbourhood’s understanding.”
Saffron Growers Association accuses Kashmiri cement plants of causing dust pollution
09 January 2024India: The Saffron Growers Association (SGA) has said that cement plants in Kashmir are causing dust pollution, to which the association attributed the decline of the local saffron industry. Down to Earth News has reported that the SGA alleges that the state’s traditional crop has ceased to be profitable because of extra costs arising from the fall of dust during flowering season. The association added that pollutants such as nitrous oxides (NOx) and sulphur dioxide (SO2) can also affect saffron’s growth.
The SGA called on authorities to regulate the construction of cement plants and their emissions more closely.
